That's why I would love to see more Docker containers and docker-compose.yaml files for tools shared on HN. A Docker container for this would be super simple to build using an official Ruby Docker container and it would save so much time for anyone who wants to try the tool.
- You're running Linux (or have access to a Linux box)
- The box running Linux is x86_64
- You have a modern kernel set up
- The box has a bunch of ram
- The box has a bunch of disk space (for installing Docker)
Docker forces you to have modern Intel-based hardware. Which excludes people with stuff like the Novena[1] or an old Thinkpad (because 32bits).
I'll be honest I've not been keeping up with Docker. It shows, right?
Docker is useful for trying out cli interpreters like this, iojs, or any thing else of the sort. I wouldn't want to use docker if I planned on keeping it around to use more than a couple of times though.
docker exec -it $NAME /bin/bash
docker run --rm -it $NAME /bin/bash
